Move logic for making reactive scope decls all reactive

InferReactiveIdentifiers has some extra logic to find identifiers declared in 
the same scope, and promote non-reactive identifiers to reactive if they appear 
inside a reactive scope (reactive scope == scope with one or more (reactive) 
dependencies). Even though the identifier alone might not be technically 
reactive (have no reactive inputs), it can get re-recreated if the scope 
re-evaluates. 

We can now do this during PruneNonReactiveDependencies as we exit out of each 
scope.
